This invention relates to improvements in hullers for peas, beans, and other green legumes and more particularly to a huller adapted to home use.

While the present invention is adapted for home use, it is to be understood that it may also be used commercially.

The primary object of the present invention is to provide a huller for green legumes that is simple and effective in operation, and that is sufiiciently inexpensive to become regular household equipment.

A preferred embodiment of this invention is illustrated in the accompanying drawings in which:

Fig. 1 is a perspective view of the device;

Fig. 2 is a transverse section therethrough; and

Fig. 3 is a cross section therethrough.

With more detailed reference to the drawing the huller housing generally designated as I, comprises cooperating base sections 2 and 3 so shaped as to fit firmly to a work surface, such as a table, and to be secured thereto by screws or other fastening means. The base sections extend upward- 1y at their abutting surfaces, see Fig. 1, to receive identical casing members 5 and 6, preferably circular in shape, that may be made integral with the base sections 2 and 3 or which may be secured thereto. The casing members 5 and 6 are detachably secured together with their inner faces abutting, by means of bolts 1 through coinciding holes 8 in the respective casing sections, or other suitable fastening means may be used.

Each of the casing members 5 and 6 has a plurality of radial grooves, designated as H and I2, respectively, accurately formed on the inner face thereof and so positioned that the grooves on the inner face of one casing member coincide with the radial grooves on the inner face of the abutting casing member, so that when the casing members 5 and 6 are secured together the radial grooves II and i2 coact to form radial holes.

Each of the casing members 5 and 6 has an axial opening, 9 and [0 respectively, that is some larger in circumference than the circumference of the green legumes.

Elongated radial pins M are received by the openings formed by the respective radial grooves I l and i2. These elongated pins are somewhat longer than the length of the radial holes and the outer, peripherial end is formed as a head to facilitate manual adjustment of each pin. The inner ends of the elongated pins extend into the axial opening 9-10 and are cut at an angle, as

2 Claims. (Cl. 13030) 2 slown in Fig. 2, to form a knife or cutting edge I While the radial holes and the pins received thereby are shown to be four in number, and that number has been found to be practical, I do not limit myself to any particular number of radial holes and pins.

In the operation of the device the bolts 1, or other fastening means, are loosened and the radial pins adjusted so that the cutting edge or knife lb, of each radial pin, is so positioned as to cut the hull or shell of the peas or beans B or whatever is to be shelled. The bolts are then tightened to hold these pins with their cutting ends in adjusted position. The end of the pea pod, for example, is thrust into the axial opening I!) in which the knives are positioned, with one hand, and the other hand receives and pulls it through, subjecting the hull to the action of the knives. The out hull may then be shaken over a suitable container to dislodge the peas so that they will fall thereinto, and the hull is discarded. and the operation repeated.

It is to be pointed out that the device may be readily adjusted for use with green legumes of different kinds and size or for marked variations in size of the same kind; and that it may be easily and quickly disassembled for cleaning. Also the device may be adjusted for use with dried legumes, and in the use of the dried legumes fewer knives could be used.

Having thus described the invention, what is claimed is:

1. A huller for green legumes comprising abutting base sections, said base sections having abutting casing members, each casing member having an axial opening and each having coinciding radial grooves in the abutting faces thereof, said abutting casing members being detachably secured together so that the radial grooves form radial holes and receiving radial pins greater in length than the radial holes, each of said radial pins having a head formed on an end thereof to facilitate adjustment, and each of said pins having the inner end thereof shaped to form a cutting edge and extending into said axial opening.

2. In a huller or sheller for peas, beans and the like, abutting base sections upstanding at the abutting faces each receiving a casing section thereupon, said base sections being adapted to be detachably secured to a work surface as by screws, each casing section having an axial opening therein greater in circumference than the diameter of the pea or bean, the inner face of each casing section having a plurality of radial grooves greater in'iength than "the radial 'groove, :ithe'" outer, peripheral end of said radial pin' being' shapedvto form a head to facilitate manual adjustment, the inner end of each radial pin being met "coincide'with like radial groov'es m the" inner face of the other of said casing sections,

shaped to form a cuttin edge andiextending-into said axial opening, said radial pins being held in": adjustedpositions by securing the inner faces of said casing sections togetherr'" FRED "A'. BLACKJsi REFERENCES CITED The following references are of record in the file of this patent:
